JAMES V. CONNERY, OF PHILADELPHIA, PENNSYLVANIA.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 349,568, dated September 21, 1886 Application lileil July Q0, 1886.

To aZZ whom it may concern:

Be it k-nown that l, JAMEs XV. CONNERY, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in SteamBoilers, of. which the followingis a full, clear, and exact description.

.The objects of this invention are to provide vertical or upright steam boilers or generators with greater water-space and larger evaporating-surface; also, to facilitate the access to the iiues for cleaning and repairs, and also to utilize the heat more effectually than is common in this class of boilers.

rIhe invention consists in an upright steamboiler having an upper section combining the functions of boiler and steam-dome, it being connected with the water-space of the boiler proper by passages of less diameter than its evaporatingarea, and to this end being spher ical or globular, or part-ly so, or ofthe shape of an inverted truncated cone, said section being also removable.

The invention also consists in interposing between the smoke-stack and crown or ilue sheet a revoluble casing providedwith a door, whereby access may be had to the interior of the smokechamber surrounding the upper section of the boiler for repairs, cleaning, and the like.

The invention also consists in the construc tion and arrangement ofthe steam outlet or service pipes, whereby theyare' not disturbed in getting at the flues or other inner parts.

The invention also consists in a certain delecting medium for throwing the heat upon the upper steam generating and containing section. In the accompanying drawings, in the several gures of which like parts are similarly designated, Figure l is a partly top and partly sectional plan view; Fig. 2, a similar elevation; and Fig. 3 is a similar elevation of another form of upper section or head.

The fire-box a, jacket b, water-space c, and fire-dues d therein may be of usual construction and arrangement, substantially asshown. The iiue or crown sheet e has a central opening, f, over which is secured the boiler section or head y. The base of this section is provided with a flange, h, through which bolts i Serial No. 208,515). (No model.)

are passed to secure it to the flue-sheet around the opening f, and so that it may be readily removed for repairs, cleaning, &c. This section g, which, as will presently appeal', subserves thepurposes of a generator and steamdome, is of increasing diameter from its plane of connection with the fine-sheet upward, and to this end may be trunco-conical, as in Fig. 2, or globularor spherical, as in Fig. 3. The section g and water-space o are further connected by pipesj, the said pipes opening into said section at or near its greatest diameter. These pipes, with the openingf, insure a thorough circulation of the water through the Water-space and section, and insure the` constant submersion of the fire-dues. It will be observed that the Water stands 'in the sec tion g on or about on a level with the openings thereinto of the pipes j, whereby is gained a large evaporating-surface. Above such water-level the section affords a steamdome. YThe pipes j in the spherical section v are preferably curved, so as to make a good join-t with the section. Plates (one or more) k are disposed around the section at an inclination thereto, so as to deflect the heat upon the section, and these deflector-plates are bolted to the 'Hue-sheet, substantially as shown iu Fig. 2. The stack-basc Z is supported upon the section g by vmeans of the iiangcd columnsm, which latter are afiixed to the said section, and the said columns serve to receive the steam outlet or service pipes o.

' Between the nue-sheet and the stack-base is arranged a revoluble shell, p, having a door, q, provided with a hand-grip, r. The door is readily removable to gain access to the interior of the smoke-chamber, and the shell p is revoluble, so as to bring the doorway to any and all portions of the boiler. I deem it essential to have the lower portion of the section g angular or curvilinear, so. as to avoid the dangersincident to a flat crown-sheet When in close proximity to the Water-line and direct action of the products of combustion. The section y is in capacity about equal to onethird of the capacityof the water-space. The section or` head g may be. further secured by a stay bolt or rod, s, passing through it and anchored to the head ofthe fire-box.

The drawings indicate the use of four pipes, j, and. also three service-pipes, o; but obviousl y these numbers may be increased or diminished at pleasure.

What I claim is- 1. An upright steam-boiler having an upper section connected with the water-space by a series of passages, fj, and increasing in diameter as it rises from the flue-sheet, and combiiiing the functions of a steam-generator and steam-dome, substantially as described.

2. In a vertical steam-generator having` a water-space, the combined steam generator and dome connected with said water-space at its foot, and also at points on or about on a level with its greatest diameter' above said foot, and of increasing diameter upward from said foot, and having suitable steam`-outl ets, substantially as described.

3. A vertical steam-generator provided with section g, shaped substantially as shown, and secured to the flue-sheet by a flange and bolts, combined with detachable pipes j, substantially as described.

4C. In a vertical steam generator or boiler,

the combination, with the jacket of the boiler and the stack-base, of a revoluble casing pro- 2 5 vided with an inlet, whereby access may be had to the interior ofthe smoke-chamber, substantially as described.

5. In a steam generator, av stack base, through which the service-pipes are passed, 3o combined with hollow columns, upon which said stack-base is supported independent of the jacket of the boiler, substantially as described.

6. In a vertical steam generator or boiler 35 provided with a section, g, defleeting plate or plates 7c, secured to the flue-sheet and inclined toward the said section, substantially as described.

In testimony whereof I have hereunto set 4.o my hand this 17th day of July, A. D. 1886.
